Almost spanning a decade OS X (pronounced as “O”-“S”-“10” not “O”-“S”-“X”) has gone through nine (9) major OS revisions of OS X to date including Public Beta.  In this review I’ve pointed out the release information for each major version of OS X as well as snapshots to help show the differences from version to version of OS X.

When it comes to OS X there have been ten (10) major releases when you include Public Beta:

For my review of OS X I used an iMac G3 700mhz Blueberry for versions 10.0, 10.1, 10.2, 10.3, 10.4, for OS X 10.5, 10.6 & 10.7 an iMac Intel Core 2 Duo & OS X 10.8 a MacBook Pro i7

Mac OS X “Public Beta”

Mac OS X Public Beta
Public Beta (Build)1H39 September 13, 2000
Media: CD-Rom
Initial Price: $29.95 (US)

The Mac OS X Public Beta (internally codenamed “Kodiak”) was an early beta version of Apple Computer‘s Mac OS X operating system Cheetah. It was the first public look at the client version of Apple’s long-awaited next generation operating system. It was based on the Developer Preview 4 (DP4) of OS X and was still very buggy. However, it demonstrated the strength of Apple’s new system software like the new Aqua interface or the Quartz drawing engine. It was sold for $29.95 U.S. at the Apple Store and was available in English, German and French. The Public Beta still had the Apple logo in center of the menu bar, but due to many user complaints, Apple moved the Apple logo back to its original place on the left side of the menu.

System Requirements:
PowerPC G3; original PowerBook G3 not supported, 128 MB of RAM, and 1.5 GB of hard disk space

Mac OS X 10.0 “Cheetah”

Mac OS X 10.0 “Cheetah”
10.0 (Build)4K78 March 24, 2001 
Media: CD-Rom
Initial Price: $129 (US)

In March 2001, Apple released the first (official) version of Mac OS X. The first release could hardly be called finished, but Apple felt that it was more important to meet the schedule. Mac OS X 10.0 was still very slow (much slower than Mac OS 9) and lacked some important features such as data CD burning or DVD video playback. Especially window resizing was extremely slow. Nonetheless, it showed many improvements over the Public Beta and it also proved that Apple was listening to the comments and criticism of the users. The lack of available software was the main problem. The first apps to appear were mostly shareware software and it took some time before the first major applications were ported to run natively under OS X.

System Requirements:
PowerPC G3 (original PowerBook G3 not supported), 128 MB of RAM, and 1.5 GB of hard disk space

10.1 (Build)5G64 September 25, 2001 
Media: CD-Rom
Initial Price: $129.95 (US)

Released in September 2001, Mac OS X 10.1 was a major step from Mac OS X 10.0. While Mac OS 10.0 felt like another beta, 10.1 was the first OS X release which could actually be used. Application launch time, window resizing and menus were significantly faster, the Dock was moveable, more customizable interface, enhanced 3D graphics performance, hundreds of drivers for third-party printers, cameras, camcorders, MP3 players and storage devices and additional network integration just to name a few of the new or improved features. Mac OS X 10.1 was a free upgrade for owners of Mac OS X 10.0. However, due to its size it was not available via Internet download, but could either be order directly from Apple for $20 or was available in the Apple Stores on burned CD-Rs.

Media: CD-Rom or DVD-Rom
Initial Price: $129.95 (US)Single User or $199(US) Family Pack

The codename of this version of Mac OS X became publicly known long before the release of 10.2 and therefore Apple decided to officially refer to this version of Mac OS X as Jaguar. Jaguar improved the performance of Mac OS X by featuring Quartz Extreme, a new version of Quartz that took advantage of the graphics accelerator cards on the modern Macs. The Mail application now had a built-in Spam mail filter, which was considered to be one of the best available. Furthermore, Apple added handwriting recognition called Inkwell. Inkwell was based on Apple’s Newton handwriting recognition. New applications were also introduced such as iChat, QuickTime 6 and Sherlock 3 (and also adding a classic-Mac OS-like quick search to the Finder). Apple also added Bluetooth support and introduced Rendezvous. Another feature that was included on the demand of the users were the spring-loading folders which were available under Mac OS 9, but were missing in the first two releases of Mac OS X. Jaguar was sold for $129 U.S.

10.3 (Build)7B85 October 24, 2003
Media: CD-Rom or DVD-Rom
Initial Price: $129.95 (US)Single User or $199(US) Family Pack

At WWDC 2003, Apple announced Mac OS X 10.3 Panther. Panther introduced lots of new features such as new window management Exposé, improved Finder, AES-128 encryption for personal files, enhanced version of Preview, faxing, faster Mail, and Font Book; a font management tool. Also, the iDisk access and synchronization was significantly improved. However, two new features got most attention: Fast User Switching and Xcode. Fast User Switching was one of the most eagerly awaited features that enabled users who shared a Mac to switch between accounts without quitting applications and logging out. Because of the graphic power of Mac OS X, the switching between users was animated by transforming the current desktop to a 3D Cube and rotating it to the new account. Xcode was a new development tool for Mac OS X applications. It improved the speed of compiling applications significantly, for instance by distributing compile workload across idle computers on a network. Panther was sold for $129 U.S.

10.4 (Build)8A428 April 29, 2005 
Media: DVD-Rom, CD-Rom (Special Order Only) 
Initial Price: $129.95 (US)Single User or $199(US) Family Pack

Mac OS X version 10.4 “Tiger” is the fifth major release of Mac OS X, Apple’s desktop and server operating system for Macintosh computers. Tiger was released to the public on April 29, 2005 as the successor to Mac OS X v10.3 “Panther”, which was released 18 months earlier, and was superseded by Mac OS X v10.5 “Leopard” on October 26, 2007, after 30 months, making Mac OS X v10.4 the longest running version of the Mac OS X operating system. Some of the new features include a fast searching system called Spotlight, a new version of the Safari web browser, Dashboard, a new ‘Unified’ theme, and improved support for 64-bit addressing on Power Mac G5s. Mac OS X x10.4 “Tiger” was included with all new Macintosh computers, and was also available as an upgrade for existing Mac OS X users, or users of supported pre-Mac OS X systems. The server edition, Mac OS X Server 10.4, was also available for some Macintosh product lines. Tiger is also the first version of any released Apple operating system to work on Apple-Intel architecture machines (Apple machines using x86 processors.) The Apple TV, as released in March 2007, ships with a customized version of Mac OS X v10.4 branded “Apple TV OS” that replaces the usual graphical user interface with an updated version of Front Row. Six weeks after its official release, Apple had delivered 2 million copies of Tiger, representing 16 % of all Mac OS X users. Apple claimed that Tiger was the most successful Apple OS release in the company’s history. At the Worldwide Developers Conference on June 11, 2007, Apple CEO Steve Jobs announced that out of the 22 million OS X users, more than 67 % were using Tiger.

10.5 (Build)9A581 October 26, 2007 
Media: DVD-Rom
Initial Price: $129.95 (US)Single User or $199(US) Family Pack

Mac OS X version 10.5 “Leopard” is the sixth major release of the Mac OS X operating system for Apple’s Mac line of personal computers, and is the successor to Mac OS X v10.4 “Tiger”. Leopard was released on October 26, 2007, and is available in two variants: a desktop version suitable for personal computers, and a server version, Mac OS X Server. Apple offers a reduced-cost upgrade to people that purchase new Apple computers between October 1, 2007 and December 29, 2007 that do not already have Mac OS X v10.5 pre-installed or a Leopard upgrade DVD included. According to Apple, Leopard contains over 300 changes and enhancements,covering core operating system components as well as included applications and developer tools. Leopard introduces a significantly revised desktop, with a redesigned Dock, Stacks, a semitransparent menu bar, and an updated Finder that incorporates the Cover Flow visual navigation interface first seen in iTunes. Other notable features include support for writing 64-bit graphical user interface applications, an automated backup utility called Time Machine, support for Spotlight searches across multiple machines, and the inclusion of Front Row and Photo Booth, which were previously only included with some Mac models. Apple missed Mac OS X v10.5’s release time frame as originally announced by Apple CEO Steve Jobs. When first discussed in June 2005, Jobs had stated that Apple intended to release Leopard at the end of 2006 or early 2007. A year later, this was amended to “Spring 2007”; however on April 12, 2007, Apple issued a statement that its release would be delayed until October 2007 because of the development of the iPhone.

Steve Jobs first announced Snow Leopard at WWDC on June 8, 2008, and it was privately demonstrated to developers by Senior Vice President of Software Engineering, Bertrand Serlet. A first public demonstration was given on WWDC 2009 by Senior Vice President of Worldwide Marketing, Phil Schiller and Serlet. Snow Leopard will ship on August 28, 2009 and an upgrade will be available for existing Leopard users for $29 U.S., or up to five computers with the family pack at $49 U.S. For a qualifying computer bought after June 8, 2009, the upgrade will cost $10 U.S. (with proof of purchase). Tiger users may upgrade by purchasing the Mac Box Set, a single package which will include Snow Leopard, iLife ’09, and iWork ’09. The update to Mac OS X will focus on improving performance, efficiency and reducing its overall memory footprint, rather than new end-user features. This will also be the first Mac OS release dating back to System 7.1.2 that does not support the PowerPC architecture as Apple now intends to focus on its current line of Intel-based products.

Mac OS X v10.7 “Lion” was released on July 20, 2011. It includes support for the Mac App Store, and brings many other developments made in Apple’s iOS, such as an easily-navigable display of installed applications, to the Mac. Changes made to the GUI (Graphical User Interface) include the Launchpad (similar to the home screen of iOS devices), auto-hiding scrollbars that only appear when they are being used, and Mission Control, which unifies Exposé, Spaces, Dashboard, and full-screen applications within a single interface. Apple also made changes to applications: they resume in the same state as they were before they were closed (similar to iOS). In addition to this, documents auto-save by default so users don’t have to worry about manually managing their documents.

System Requirements:
Intel Core 2 Duo, Core i3, Core i5, Core i7, or Xeon processor, 2 GB of RAM, 7 GB of disk space, and Mac OS X v10.6.6 or later (v10.6.8 recommended)

Initial Price: $19.99 (Mac App Store)

OS X Mountain Lion (version 10.8) is the ninth major release of OS X. OS X Mountain Lion was released on July 25, 2012. It gains features from iOS, such as Notes and Reminders as applications separate from Mail and Calendar, in addition to those iOS features introduced in Mac OS X Lion. OS X Mountain Lion replaces iChat with Messages, which includes support for iMessage, allowing users to send unlimited messages to other Macs (running 10.8 or later), iPhones, iPads and iPod Touches (running iOS 5 or later). It also includes the latest version of the Safari web browser, Safari 6. Another feature from iOS 6 included in Mountain Lion is Notification Center, a sidebar pane that provides an overview of alerts from applications. It displays notifications until the user completes an associated action, rather than requiring instant resolution. OS X Mountain Lion received positive reviews, with critics praising Notification Center, Messages, and speed improvements over Mac OS X Lion, and criticizing Game Center for lack of games. Mountain Lion sold 3 million units in the first four days, making it Apple’s most successful Mac release to date.
